Control Strategies of Asymmetric Strip Shape in Six-High Cold Rolling Mill

摘要: It is a complicated problem for cold-rolled strip to improve asymmetric shape in production. A roll system and coupled model of six-high cold rolling mill was established with finite element method estimate the effect intermediate shifting, tilting, symmetric bending technologies on profile. To reduce defects as much possible, some control strategies were proposed, including tilting work roll. The combinations these three can effectively eliminate defects. Finally, closed-loop flatness at last stand given, function also designed tandem mill.
